Different “routes” to a cognitive map: dissociable forms of spatial knowledge derived from route and cartographic map learning

An important, but as yet incompletely resolved, issue is whether spatial knowledge acquired during navigation differs significantly from that acquired by studying a cartographic map. This, in turn, is relevant to understanding the generalizability of the concept of a “cognitive map,” which is often likened to a cartographic map. On the basis of previous theoretical proposals, we hypothesized that route and cartographic map learning would produce differences in the dynamics of acquisition of landmark-referenced (allocentric) knowledge, relative to view-referenced (egocentric) knowledge. We compared this model with competing predictions from two other models linked to route versus map learning. To test these ideas, participants repeatedly performed a judgment of relative direction (JRD) and a scene- and orientation-dependent pointing (SOP) task while undergoing route and cartographic map learning of virtual spatial environments. In Experiment 1, we found that map learning led to significantly faster improvements in JRD pointing accuracy than did route learning. In Experiment 2, in contrast, we found that route learning led to more immediate and greater improvements overall in SOP accuracy, as compared to map learning. Comparing Experiments 1 and 2, we found a significant three-way interaction effect, indicating that improvements in performance differed for the JRD versus the SOP task as a function of route versus map learning. We interpreted these findings as suggesting that the learning modality differentially affects the dynamics of how we utilize primarily landmark-referenced versus view-referenced knowledge, suggesting potential differences in how we utilize spatial representations acquired from routes versus cartographic maps.     

国内元认知的相关研究及其展望

元认知这一概念是由美国发展心理学家弗莱维尔(Flavell)在1976年正式提出来的。至今,学者们对其进行了广泛深入的研究,无论是在理论还是实证方面都取得了丰硕的成果。文章首先对元认知(metacognition)的概念作了阐述,接着陈述了当前关于元认知的结构比较认可的两分法以及三分法,并提出了关于元认知结构的看法。然后对目前国内元认知的相关研究做一综述,最后文章在分析过去研究所存在问题的基础上提出了对元认知研究的展望。     

汉字记忆中错误联接的码相加效应

采用错误联接的实验范式考察汉字记忆中的码相加效应。实验1采用形码加义码,结果发现对义似形似组的特征诱字错误再认率显著高于义异形似组的。实验2采用形码加音码．结果发现对音似形似组的诱字的错误再认率显著高于音异形似组的。研究表明汉语记忆中的错误联接存在码相加效应。研究结果可用激活混淆来源理论解释。

Sudden Death and Gradual Decay in Visual Working Memory

ABSTRACT— General Douglas MacArthur remarked that "old soldiers never die; they just fade away." For decades, researchers have concluded that visual working memories, like old soldiers, fade away gradually, becoming progressively less precise as they are retained for longer periods of time. However, these conclusions were based on threshold-estimation procedures in which the complete termination of a memory could artifactually produce the appearance of lower precision. Here, we use a recall-based visual working memory paradigm that provides separate measures of the probability that a memory is available and the precision of the memory when it is available. Using this paradigm, we demonstrate that visual working memory representations may be retained for several seconds with little or no loss of precision, but that they may terminate suddenly and completely during this period.     

在心理治疗中审视积极与消极情绪的关系及作用

心理治疗中长期存在两种倾向：力图减少消极情绪、认为这样可以自动增加积极情绪。该文分析并总结了有关积极与消极情绪的关系及作用的实证研究和综述,主要得出三个结论：1）积极与消极情绪有三种关系：负相关、相互独立、部分重合,具体表现出哪种关系要视实际情况而定。2）过多的积极情绪对认知、行为、健康有消极作用。3）适当的消极情绪对认知、行为、健康有积极作用。因此,在进行心理治疗或研究时,应根据实际情况．明确对象并选择正确方法。     

儒家哲理特征与文化间对话——普遍主义还是非普遍主义

Confucianism is a rather typical non-universalism, even though it does believe that its own doctrines are indeed the ultimate truth, and denies the validity of any higher, universalist meta-standard. Therefore, when facing the contemporary culture intercourse, Confucianism advocates genuine discourse: It rejects any cultural conflict to-the-death, refuses to engage in universalist competition and antagonism, and maintains a mutually-beneficial interaction with other cultures. However, it also adheres to a “free-to-terminate-relations” principle, which implies that any side is free to terminate, at any time, all potential and actual interactions, whenever it feels that its original cultural vitality is threatened. In other words, cultural interactions must only occur when the cultural uniqueness and independence of all participating sides is guaranteed.     

Glimpses of a one-speed mind: Focus-switching and search for verbal and visual, and easy and difficult items in working memory

We investigated focus-switching and search rates in an N-Back task for stimuli presumably encoded either in a phonological/semantic or an abstract-visual format. Experiment 1 used Chinese characters and tested Chinese speakers and non-Chinese speakers; character frequency and visual complexity were also manipulated. Experiment 2 presented Chinese characters and English words to non-Chinese English speakers. Effects of focus-switching on accuracy were larger for abstract-visual stimuli and for more difficult stimuli; effects on RT were larger for abstract-visual stimuli, but there was no effect of difficulty, with the exception of the most difficult stimulus set in Experiment 1. Search slopes outside the focus of attention did not covary with either type of code or item difficulty. The decline in accuracy over set-size was stronger for the items coded in abstract-visual format. This suggests that item availability is sensitive to robustness of the memory representations, but item accessibility is not. The data fit well with a model of STM in which a fixed number of ‘slots’ are searched at a constant rate, regardless of the slot’s contents.     

Effects of Personality on Individual Earnings: Leadership Role Occupancy as a Mediator

Purpose  The purpose of this study was to investigate the direct and indirect effects of personality characteristics on individual earnings and to examine a person’s leadership role occupancy as the potential mediator in the personality–earnings relationship. Design/Methodology/Approach  Longitudinal survey data were collected from a sample of 209 individuals. Earnings were measured 6 years after the personality variables. Findings  Two personality traits, i.e., Social Potency and Achievement, predict individual earnings longitudinally. The effects of personality were partially mediated by the person’s occupancy of leadership roles in the workplace. For those occupying similar leadership positions, people higher in social potency still have greater earnings. Implications  These findings lend support for personality assessment in personnel selection and have important implications for leadership development and individual career success. Originality/Value  Previous research suggests that personality influences individual earnings beyond the effects of traditional human capital variables. This study is among the first to distinguish personality’s direct and indirect (through leadership role occupancy) effects on individual earnings. The findings provide direct support for the incentive-enhancing property of personality as well as indirect support for the trait activation theory on the personality–earnings relationship.
